NATURE OF PROPOSAL
I. To IRAN all F-2 Foils and modify them to provide:
1. Pilot control over raising, lowering, and advancing of records.
2. A mechanical down stop to accurately position the record in the duct.
3. A new pawl which will mechanically index a single record at each
actuation (this will eliminate record skipping). This pawl is
currently being incorporated in all new F-2 foils.-
Reduced seal interference, by replacing the aft inflatable seal
with a fixed hard faced seal.
Smoother transport of records by modifying the pusher assembly to
get better metering of the damping fluid.
6. A simplified actuator change by adding a connector,to the actuator,
leads for both the door and the record actuator.
7. A new control panel which is ccmpatable with the revised system.
8. In the'process of this rework, the F357-2 hatches will receive an
IRAN.
No Service Bulletin required. All work to be done at the factory per
a Depot Rework Order request.
REASCK FOR PORPOSAL
The existing F-2 Foil configuration works well if properly adjusted. However,
it is difficult to adjust correctly even if all parts are in good condition.
In addition to adjustment difficulties, the pilot has no control to free a
stuck record or advance a record should the pawl stick. The proposed changes
eliminate, or reduce, the likelyhood of malfunctions that have been experienced
with this equipment.' These changes will also reduce the maintenance required
to keep these units operational.
